The Keysight 10771A Angular Reflector, used in the Keysight 5530 Laser Calibration System, is ideal for precision calibration applications. Paired with the 10770A Angular Interferometer, it is used to measure pitch and yaw motions along each axis that a machine tool or measuring machine travels. The system can help quickly locate and evaluate unwanted angular motion.

As part of the 5530 system, the Keysight 10771A is a powerful diagnostic tool that finds the causes of angular positioning errors -- information that is critical in making replace or rebuild decisions for older machine tools.
